A fb patch for the GX allready exists...  See below and check the
fbdev archives for the patch.  Looks like it depends on some VSA magic

A framebuffer driver for the display controller in AMD Geode GX
processors (Geode GX533, Geode GX500 etc.).  Tested at 640x480, 800x600,
1024x768 and 1280x1024 at 8, 16, and 24 bpp with both CRT and TFT.  No
accelerated features currently implemented and compression remains disabled.

This driver requires that the BIOS (or the SoftVG/Firmbase code in the
BIOS) has created an appropriate virtual PCI header.
